Stormwater Chambers are used as underground infiltration or retention/detention systems in replacement of ponds, concrete structures or pipe and stone installations, and can either replace or work in conjunction with bioswales. They are installed in trench or bed configurations according to site restrictions or client preference.
For commercial applications, the placement of stormwater management systems beneath parking areas allows for further site development without sacrificing land area. Since retail development is often directly related to the number of parking spaces available, sub-surface installation of stormwater chambers maximizes land use and capability of additional parking spaces. These systems also meet local stormwater management regulations.


  • Allows for more controlled infiltration into the ground
  • Replenishes the surrounding soil and aquifer
  • Decreases health liability issues such as West Niles breeding grounds for mosquitoes, or drowning
  • Avoids redirecting stormwater to a watercourse and potentially overloading or polluting our natural surroundings and resources
  • Frees up land for further development such as athletic fields or parking areas
  • Stormwater chambers effectively serve environmentally sensitive areas while making valuable land available for parking lots, athletic fields and other applications
  • The high capacity, open bottom chambers provide greater storage and much higher infiltrative capability than conventional pipe and stone systems
  • As a replacement for retention ponds, stormwater chambers alleviate insurance concerns and loss of valuable land area
  • Less area is required compared to conventional systems
  • Stormwater chambers have interior support panels for added strength
  • Similar to the aqueducts used by the ancient Romans, the arch design has proven to be one of the strongest structural engineering designs. As a more modern example, a suspension bridge is an upside-down arch with the tension cables acting as the keystone
